If I have 5 nodes and I wish to maintain 1 Master and 2 Workers on each node, so in total I will have 5 master and 10 Workers.
Now to maintain that setup I would like to query spark regarding the number Masters and Workers that are currently available using API calls and then take some appropriate action based on the information I get back, like restart a dead Master or Worker. Is this possible? does Spark provide such API?
